The thickness of avian blood-gas barrier: qualitative and quantitative observations.
(1982)
Gas exchange in the avian lung takes place across a blood-gas barrier formed, as
in other air-breathing vertebrates, by three essential components, an epithelial cell,
a basal lamina, and an endothelial cell. The thickness ...
Diacetyl—A growth and toxin inhibitor of Aspergilli
(University of Nairobi, 1985)
Diacetyl (2,3-butanedione) a food additive, was found to be very effective in inhibiting growth and toxin production of Aspergillus flavus, A. versicolor and A. ochraceus when grown on synthetic liquid media and on natural ...
Morphometrics of the avian lung. 3. The structural design of the passerine lung
(1984)
The lungs of 46 adult, wild passerine birds belonging to 8 species have been analysed morphometrically, both by light and electron microscope. Volumes were estimated by point counting, surface areas by intersection counting, ...
Testing a von Liebig Crop Response Function against Polynomial Specifications
(1985)
Crop responses to fertilizers traditionally have been specified as polynomial functions. Recently, criticisms were raised against such specifications because they force substitution between nutrients and overestimate the ...
Morphometrics of the avian lung. 2. The wild mallard (Anas platyrhynchos) and graylag goose (Anser anser).
(1982)
The lungs of 5 wild mallard ducks (Anas platyrhynchos) and 5 feral graylag geese (Anser anser) of mean body weight 1.04 and 3.84 kg, respectively, were fixed in situ by intratracheal infusion of 2.3% glutaraldehyde, pH 7.4 ...
A scanning electron microscopic study of the air and blood capillaries of the lung of the domestic fowl (Gallus domesticus)
(Birkhäuser-Verlag, 1982)
Air and blood capillaries of the lung of the domestic fowl constitute the functional gas exchange units. They anastomose profusely and interlace with each other in 3 dimensions. Air capillaries are not blind-ending tubules ...
The effects of temperature on muscle pH, adenylate and phosphogen concentrations in Oreochromis alcalicus grahami, a fish adapted to an alkaline hot-spring
(Wiley, 1983)
The concentrations of phosphorylcreatine (PCr), adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), inorganic phosphate (Pi), pyruvate and lactate were determined in freeze-clamped ...
A morphometric analysis of the lung of a species of bat.
(1982)
The lungs of five adult Epauleted Fruit-bats (Epomophorus wahlbergi) of mean body weight 96 g were analysed morphometrically. The lung volume per unit body weight was 0.043 cm3/g, the surface area of the tissue barrier ...
Morphometrics of the avian lung. 4. The structural design of the charadriiform lung
(1987)
The lungs of five charadriiform species of bird, two of which are good divers and three predominantly flyers (soarers and gliders) have been analysed by morphometric techniques. Largely the morphometric structural values ...
